About this product

The double-wall side slotted tray is a one-piece, unglued container that locks together using mechanical friction. Packers roll the long side walls over 180 degrees, trapping the corner flaps. This creates a rigid, double-thick perimeter that resists side crushing and hides raw corrugated edges for a clean retail presentation.

Because it uses a side-slotted flat blank rather than a cross-folder layout, it reduces corrugated waste during manufacturing. It relies entirely on manual folding and base slots, making it a strong choice for pack benches and retail staging where automated gluing lines are unavailable.

Common uses

  • Retail shelf-ready packaging
  • Dense produce packing
  • Internal warehouse kitting
  • Heavy-duty flat goods transport

Retail display, produce packing, and warehouse staging

Retail shelf-ready packaging

The 180-degree roll-over hides the raw flutes of the corrugated board along the long sides. This creates a smooth frame for consumer goods. The double-thick walls prevent the tray from bowing outward when stacked on retail shelves.

Dense produce and agricultural packing

For heavy fruits or vegetables, the reinforced side walls provide necessary stacking strength. The glueless construction keeps adhesive away from fresh food environments.

Internal warehouse kitting

Warehouse teams can erect these trays on demand to move heavy metal or electronic components between workstations. The mechanical locks hold firm under dense payloads, and the trays can be knocked down flat when not in use.

Heavy-duty flat goods transport

Books, tiles, and other dense, flat items benefit from the rigid side protection. The double-wall sides absorb lateral impacts during palletized transit.

Retail, agricultural, and industrial fit

Retail merchandising

Brands moving goods directly from pallet to shelf benefit from the clean rolled edges, which frame the product without exposing rough corrugated cuts.

Agricultural distribution

Growers packing dense, heavy produce rely on the double-wall sides to support palletized weight without the risk of hot-melt glue failing in humid environments.

Industrial staging

Assembly lines use these rigid trays to organize heavy components. The unglued setup means trays can be formed exactly when needed at the pack bench.

When to consider glued or end-rolled trays

High-speed automated packing

If your facility uses plunger-style tray erectors or hot-melt gluing lines, a standard glued tray will drastically reduce assembly labor compared to manual folding.

End-heavy stacking loads

If the primary crush risk or load-bearing requirement falls on the short ends of the tray rather than the long sides, an end slotted tray shifts the double-thick roll-over to the width panels.

Parcel and courier shipping

Because the top is completely open and the friction tabs can pop under drop shock, shipping single orders through a courier network requires a sealed master carton or a fully enclosed mailer.

Close variants and lookalike dielines

The closest library neighbors include 0454, 0451, 0452. Use this as a variant check if a buyer brings an old code, sample, or dieline that looks close. The deciding details are usually the lock, slot, closure, wall build, part count, or fold sequence.

Board thickness, stripping, and packing labor

Board thickness and foldability

The 180-degree roll-over hinge is highly sensitive to material thickness. Fine flutes fold crisply. Heavy double-wall boards can crack at the hinge or prevent the locking tabs from reaching the base slots unless the fold clearances are perfectly calibrated.

Die-cutting and internal waste

The base slots required for the locking tabs create small internal pieces of scrap. Your production run will require flatbed or rotary die-cutting, and the converter must actively manage this stripping waste to prevent press jams.

Manual assembly labor

Operators must fold the end walls, tuck the corner flaps, and roll the side walls over to lock the tray. This requires repetitive thumb force and two hands, which should be factored into your pack-bench labor costs.

Transit route and closure

The open top exposes the product. If the tray will move through mixed-carrier networks rather than staying on a pallet, you will need to plan for a master shipper or a secure lid.

Corner slots, lock tabs, and fold clearances

Corner slot profiles

The slots where the corner flaps meet the side walls can be cut straight or with a rounded offset. Rounded slots are often easier for the factory to strip cleanly, though they may slightly loosen the corner wrap.

Lock tab friction

The width and depth of the distal locking tabs can be adjusted to change how tightly the tray holds its shape. A tighter fit increases security but requires more operator force to assemble.

Fold clearance tuning

The distance between the parallel creases on the roll-over panel can be widened to accommodate thicker board grades, ensuring the inner wall reaches the base slots without bowing.

Board and packing details

Material efficiency versus cross folders

Older tray designs often use a cross-folder layout, which creates large L-shaped offcuts of wasted board. This side-slotted architecture keeps the corner material attached to the end panels, improving the number of trays that fit on a single sheet of corrugated board.

Additional notes

Print surface and high-gloss coatings

The base and outer side panels offer excellent flat surfaces for printing. However, applying high-gloss varnish or slick coatings can reduce the friction on the locking tabs, increasing the risk of the tray springing open under tension.

Alternative open trays

0452: Glued Open Tray

A simpler open tray designed for automated hot-melt gluing rather than manual friction locks.

0423: Cross Folder Tray

Achieves a similar double-wall side profile but uses a less material-efficient flat blank layout.

FAQs

Assembly and Packing

Does this tray require glue or tape to hold its shape?

No. The tray relies entirely on mechanical friction. The long side walls roll over the corner flaps, and tabs on the edges snap securely into slots on the base panel.

Shipping and Route

Can I ship this tray directly through a parcel courier?

Not on its own. The open top exposes the product. Rough handling can cause the friction tabs to pop open. Parcel delivery usually requires an outer master carton or a secure lid.

Material and Board

Can this tray be made from heavy double-wall corrugated board?

It is possible, but it requires careful testing. The 180-degree roll-over fold is highly sensitive to board thickness. If the board is too thick, the hinge can crack, or the locking tabs may fail to reach the base slots. Fine or medium flutes generally perform best.

Production and Tooling

Does this tray require custom cutting dies?

Yes. Because of the internal base slots and specific locking tabs, this tray must be produced on a flatbed or rotary die-cutter. It cannot be manufactured on a standard rotary slotter.

Inserts and Fit

Will the rolled side walls interfere with custom inserts?

The double-thick side walls slightly reduce the internal width of the tray. If you are pairing this tray with a custom insert or partition, the internal dimensions must account for that rolled inner layer.

Comparison

Why choose this over a standard glued tray?

This style is a strong choice when you need high side-crush resistance and clean presentation edges, but do not have automated gluing equipment at your packing station. It allows warehouse teams to erect rigid trays on demand.

Assembly and Packing

Can we run this tray on an automated folder-gluer?

No. The unglued mechanical design means it ships entirely flat. Erection requires manual pack-bench labor or highly specialized plunger-tray equipment.

Storage and Handling

How are these trays delivered and stored?

They ship flat as a single piece of corrugated board. Because they do not have pre-glued joints, they stack densely on a pallet, saving warehouse space until they are needed.
